What is the coolant temp reading on the scan tool?
Thank you for posting your question.
Your business is very valuable to us.Thank You ***** *****
190*F is the coolant temp reading from the scanner
When the coolant temperature is below 91°C (195°F), the thermostat valve remains closed. This prevents circulation of the coolant to the radiator and allows the engine to warm up quickly. After the coolant temperature reaches 91°C (195°F), the thermostat valve will open.
Temperature should reach over 223°F to turn the fans on. If not then the thermostat may be bad.
Are both heater hoses the same temperature?
one heater hose is 160 F and the other is 130F
Heater core is probably clogged. Try flushing it with a garden hose at the heater hoses. Use a spray nozzle for more pressure and flush it both ways. If it clears up you should do a flush with some type of chemical flush like Prestone Super flush or other brand.

Also if the system is not getting hot enough to turn on fan, which is 223°F you should change the thermostat.
im gonna do the thermostat because I haven't heard the fans come on.
You should also flush the heater core with a hose while you have system open.
